Avery ★★★★★ Oct 22, 2026

The full area calibration on this 18-inch flat is spot-on across the entire surface—no edge drop-off at all. It paired perfectly with the new high stability cell I bought, and setup was straightforward. Exactly the precision I needed for my work.

Mia G. ★★★★★ Oct 21, 2026

Installing it with the new high stability cell was straightforward, and the full area calibration on my 18-inch flat came out spot-on. The precision is impressive for the price.

Evelyn A. ★★★★★ Oct 19, 2026

Finally got my new cell installed and ran the full area calibration—the ZYGO flat required a stable setup, but once dialed in, the interference patterns were crisp and consistent. Definitely worth the effort for precision work on larger optics.
